```Python
q: str = Query(default=None, max_length=50)
```

Isso irá validar os dados, mostrar um erro claro quando os dados forem inválidos, e documentar o parâmetro na *operação de rota* do esquema OpenAPI..

## Adicionando mais validações

Você também pode incluir um parâmetro `min_length`:

{* ../../docs_src/query_params_str_validations/tutorial003.py hl[10] *}

        // Test task creation with null document map
        String path = "/path/to/document.pdf";

        Tuple3<String, String, String> task = thumbnailGenerator.createTask(path, null);
        assertNull(task);
    }

    public void test_createTask_withEmptyDocMap() {
        // Test task creation with empty document map
        String path = "/path/to/document.pdf";

    }

    /**
     * Scrolls through all documents in the specified index and applies the callback function to each hit.
     *
     * @param index the name of the index to scroll through
     * @param callback the function to apply to each search hit, returning true to continue or false to stop
     * @return the number of documents processed
     */

It would also mean that if you get data from the `Request` object directly (for example, read the body) it won't be validated, converted or documented (with OpenAPI, for the automatic API user interface) by FastAPI.

Although any other parameter declared normally (for example, the body with a Pydantic model) would still be validated, converted, annotated, etc.

        }

    }

    /**

     * If the config has a timeToLive value, calculates expiration from current time.
     * Otherwise, returns the stored document expiration time.
     *
     * @param config the crawling configuration containing time-to-live settings
     * @return the document expiration date, or null if no expiration is set
     */

        fileTypeHelper.add("application/pdf", "document");
        fileTypeHelper.add("application/msword", "document");
        fileTypeHelper.add("text/plain", "text");

        String[] types = fileTypeHelper.getTypes();
        assertEquals(2, types.length);

        Arrays.sort(types);
        assertEquals("document", types[0]);
        assertEquals("text", types[1]);
    }

# Corpo - Modelos aninhados

Com o **FastAPI**, você pode definir, validar, documentar e usar modelos profundamente aninhados de forma arbitrária (graças ao Pydantic).

## Campos do tipo Lista

Você pode definir um atributo como um subtipo. Por exemplo, uma `list` do Python:

{* ../../docs_src/body_nested_models/tutorial001.py hl[14] *}

Isso fará com que tags seja uma lista de itens mesmo sem declarar o tipo dos elementos desta lista.

 *
 * <p>Because of this situation, any public method accepting an iterable should invoke the {@code
 * iterator} method only once, and should be tested using this class. Exceptions to this rule should
 * be clearly documented.
 *
 * <p>Note that although your APIs should be liberal in what they accept, your methods which
 * <i>return</i> iterables should make every attempt to return ones of the robust variety.
